Fish Shipping Prep Checklist: Stress-Free Arrival
Whether receiving or sending fish, preparation minimizes transit stress and loss. Use this structured checklist for packing, timing, and acclimation.
Pre-Ship Water Conditioning (24–48 Hours)
- Maintain pristine water: Ammonia 0, Nitrite 0, Nitrate <20 ppm
- Fast fish 12–24 hours (reduces waste during transit)
- Stable temperature (avoid last-minute swings)
Packing Materials
| Item | Purpose |
|---|---|
| Insulated Box / Liner | Temperature stability |
| Breathable Bags or Poly Fish Bags | Secure containment |
| Double Bagging | Prevent leaks |
| Plant Fiber / Paper | Reduce sliding, cushion |
| Heat or Cool Packs (seasonal) | Thermal regulation |
| Oxygen (Optional) | Extended transit for sensitive species |
Bagging Process
- Fill 1/3 water, 2/3 air (or oxygen)
- Avoid overcrowding—stock fewer fish per bag
- Add ammonia neutralizer if long transit expected
- Seal with tight rubber bands; invert into second bag opposite direction
Temperature Management
- Use appropriate seasonal pack; wrap with paper (avoid direct contact with bags)
- Include ventilation holes if using heat packs (prevent oxygen depletion)
Labeling & Timing
- Ship early week (Mon–Wed) to avoid weekend delays
- Mark "Live Fish" + orientation arrows; include acclimation insert
- Use reliable carrier with tracking updates
Receiving Checklist
| Step | Action |
|---|---|
| Inspect Box | Check damage and temperature feel |
| Open Carefully | Avoid sudden bright light |
| Float Bags | 20–30 min temperature equalization |
| Test Water (Optional) | Ammonia/pH snapshot helps acclimation decisions |
| Net Transfer | Discard shipping water to prevent pathogen introduction |
Acclimation Method (Standard)
- Float bags
- Open & gently pour fish + water into clean container
- Add tank water in small increments every 5 minutes (4–6 additions)
- Net fish to display or quarantine tank
Reducing Stress Post-Transfer
- Dim lights for 4–6 hours
- Offer small, high-quality meal only after normal swimming resumes
- Monitor respiration and coloration first 24 hours
Invertebrate Specific Notes
Shrimp and snails are sensitive to copper; confirm receiving tank has no contaminated decor. Drip acclimation preferred for Caridina.

Final Thoughts
Thorough preparation and calm, staged acclimation dramatically improve survival. A repeatable checklist eliminates rushed shortcuts that cause losses.
